Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of silver-plating auxiliary devices for chip capacitors, specifically a flat roller leveling device for a thick silicone plate. Background Technology
[0002] The thick silicone plate of the end-sealing machine is fed by a needle bed that pushes the chip capacitors into the holes of the thick silicone plate, thus fixing the chip capacitors in a clamping manner. Therefore, after the chip capacitors are successfully implanted into the holes of the thick silicone plate, the height of each chip capacitor protruding from the silicone plate surface is affected by factors such as the needle bed precision and the elasticity of the silicone in the thick silicone plate, resulting in inconsistent chip capacitor heights. This leads to significant deviations in the amount of slurry applied during subsequent slurry application. To address this issue, the existing process utilizes the high precision of the slurry spreading mechanism within the slurry spreading equipment to press down the thick silicone plate during slurry application. This forces the chip capacitors down to the bottom platform of the slurry layer during the slurry application process, squeezing any protruding chip capacitors back into the holes of the thick silicone plate, thereby resolving the issue of inconsistent slurry application.
[0003] In previous production processes, when applying slurry to chip capacitors, a thick silicone plate was pressed down to bring the chip capacitors into contact with the bottom platform of the slurry for leveling. When the chip capacitors were in contact with the bottom of the slurry platform, they overlapped and sealed with the platform bottom, generating significant tension. This caused the chip capacitors to detach from the thick silicone plate due to the tension and fall off when the slurry application process began and the thick silicone plate rose. Secondly, because the chip capacitors overlapped with the bottom of the slurry platform, the slurry on top of the chip capacitors was squeezed out, resulting in a thin or no slurry layer on top of the chip capacitors after the process was completed. Therefore, this method did not meet current requirements. To address these issues, we proposed a leveling device using a thick silicone plate with a flat roller. Utility Model Content
[0004] The purpose of this invention is to provide a leveling device for a flat plate with rollers on a thick silicone plate, in order to solve the problems mentioned in the background art, such as the flat capacitors being pulled out and falling off when they touch the bottom during slurry application, and the top slurry layer being thin or absent.

[0006] Preferably, the first displacement mechanism includes a side-mounted pallet moving cylinder installed at the rear end of the bottom of the upright, a pallet moving slider is provided below the thick rubber plate pallet, the movable end of the pallet moving cylinder is fixed to the pallet moving slider, and the pallet moving slider moves on the guide rail at the bottom of the upright.
[0007] Preferably, the second displacement mechanism includes a leveling roller moving slider fixedly disposed at the rear end of the bottom of the stand, the leveling roller moving slider is displaced on the guide rail at the bottom of the stand, and the lower end of the leveling roller mounting bracket is fixed to the leveling roller moving slider. A roller platform moving cylinder is installed on the other side of the front end of the bottom of the stand, and the movable end of the roller platform moving cylinder is fixed to the leveling roller moving slider.
[0008] Preferably, a leveling roller gear is fixedly installed at one end of the leveling roller, and a leveling roller rack is welded and fixed on the side frame of the upright, and the leveling roller rack is meshed with the leveling roller gear.
[0009] Preferably, both sides of the upper flatbed leveling platform are provided with transverse telescopic cylinders, and the movable end of the transverse telescopic cylinder is equipped with a clamping plate.
[0010] Preferably, a leveling platform lifting position sensor is installed on one side of the top plate of the support frame.
[0011] Preferably, the base plate of the support frame is provided with multiple connection holes.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. Traditional processes use a thick silicone plate to press down on the capacitor sheet, causing it to contact the bottom platform of the slurry for leveling. In this method, the capacitor sheet overlaps and seals with the platform bottom in the slurry, generating significant tension. As the thick silicone plate rises after the slurry application, the capacitor is easily pulled off due to this tension and falls. This invention employs a unique leveling roller design. During operation, a gear at one end of the leveling roller meshes with a rack fixed to the frame, causing the roller to rotate synchronously as it moves forward. This rolling pressure leveles the capacitor sheet on the thick silicone plate. This non-contact leveling method effectively avoids the tension generated between the capacitor and the platform bottom due to the seal, greatly reducing the probability of the capacitor falling off.
[0014] 2. This invention utilizes a roller leveling system to ensure that the height of the sheet capacitors on the thick silicone plate is uniform before slurry application. As the rotating leveling roller passes under the thick silicone plate, the flatness of the roller surface and the uniform pressure precisely adjust the sheet capacitors of different heights, eliminating the problem of inconsistent capacitor heights caused by factors such as needle bed precision and the elasticity of the silicone plate. In this way, during the subsequent slurry application process, each sheet capacitor can make uniform contact with the slurry, avoiding deviations in the amount of slurry applied.
[0015] 3. This utility model is equipped with automated structures such as a pallet-moving cylinder and a roller platform-moving cylinder, realizing fully automated operation of the thick silicone sheet from conveying and positioning to leveling. When the pallet-moving cylinder retracts, the pallet-moving slider drives the thick silicone sheet pallet to accurately deliver the thick silicone sheet under the upper flat leveling platform; the roller platform-moving cylinder then drives the leveling roller slider equipped with leveling rollers, accurately moving the leveling rollers to the working position. The entire process requires no complex manual adjustments. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figure 1-3 This utility model provides an embodiment of a thick silicone plate flatbed roller leveling device, including a frame 1. A platform lifting motor 6 is fixedly installed at the upper end of the frame 1. A screw transmission mechanism is installed at the output end of the platform lifting motor 6. An upper flatbed leveling platform 8 is installed at the bottom of the screw transmission mechanism. A thick silicone plate bearing tray 4 is provided below the upper flatbed leveling platform 8. A thick silicone plate 5 is provided on the upper surface of the thick silicone plate bearing tray 4. A first displacement mechanism is provided below the thick silicone plate bearing tray 4 for conveying the thick silicone plate 5 to the lower part of the upper flatbed leveling platform 8. A leveling roller 14 is installed at the rear end below the upper flatbed leveling platform 8. A second displacement mechanism is provided at the lower end of the mounting bracket of the leveling roller 14 to move the leveling roller 14 and level the product at the lower end of the thick silicone plate 5. A rotation drive mechanism is provided on the side of the leveling roller 14 to keep the leveling roller 14 rotating during the movement. Multiple connection holes are provided on the bottom plate of the frame 1.
[0022] After the platform lifting motor 6 starts, it drives the upper flat leveling platform 8 to move up and down via the screw transmission mechanism. When the first displacement mechanism operates, it moves the thick plastic sheet carrying tray 4, conveying the thick plastic sheet 5 placed on it to below the upper flat leveling platform 8. The second displacement mechanism starts, pushing the leveling roller 14 to the thick plastic sheet 5. At the same time, the rotation drive mechanism makes the leveling roller 14 continuously rotate during the movement, leveling the product on the thick plastic sheet 5 by rolling. This realizes the automated process of conveying and leveling the thick silicone sheet. The rolling leveling by the leveling roller 14 avoids the product from contacting the flat surface and generating tension, effectively preventing the product from falling and improving the stability of the processing. In addition, the rolling leveling can make the product height more uniform, providing a good foundation for the subsequent paste application process.
[0023] Please see Figure 1 and Figure 3 The first displacement mechanism includes a side-mounted pallet moving cylinder 2 installed at the rear end of the bottom of the upright 1. A pallet moving slider 3 is provided below the thick rubber plate pallet 4. The movable end of the pallet moving cylinder 2 is fixed to the pallet moving slider 3, and the pallet moving slider 3 moves on the guide rail at the bottom of the upright 1. The pallet moving cylinder 2 serves as a power source. When the cylinder retracts, its movable end pulls the pallet moving slider 3. Since the pallet moving slider 3 is connected to the thick rubber plate pallet 4, the thick rubber plate pallet 4 will move accordingly, accurately conveying the thick rubber plate 5 placed on it to the designated position below the upper flat plate leveling platform 8.
[0024] Please see Figure 2 and Figure 3 The second displacement mechanism includes a leveling roller sliding block 13 fixedly mounted at the rear end of the bottom of the support frame 1. The leveling roller sliding block 13 moves on the guide rail at the bottom of the support frame 1, and the lower end of the mounting bracket of the leveling roller 14 is fixed to the leveling roller sliding block 13. A roller platform moving cylinder 12 is mounted on the other side of the bottom front of the support frame 1, and the movable end of the roller platform moving cylinder 12 is fixed to the leveling roller sliding block 13. The roller platform moving cylinder 12 serves as a power element. When the cylinder is activated, its movable end pushes the leveling roller sliding block 13 to slide on the guide rail at the bottom of the support frame 1. Since the mounting bracket of the leveling roller 14 is fixedly connected to the leveling roller sliding block 13, it drives the leveling roller 14 to move towards the thick rubber plate 5, enabling it to reach the working position for leveling the product on the thick rubber plate 5. Through the combination of the cylinder and the sliding block guide rail, the leveling roller 14 can move flexibly and precisely, and its position can be quickly adjusted according to production needs, ensuring the smooth progress of the leveling operation.
[0025] Please see Figure 2 A leveling roller 14 is fixedly mounted with a leveling roller gear 11 at one end. A leveling roller rack 10 is welded and fixed on the side frame of the support frame 1, and the leveling roller rack 10 is meshed with the leveling roller gear 11. When the leveling roller 14 moves under the drive of the second displacement mechanism, the leveling roller gear 11 moves together with the leveling roller 14. Since the leveling roller gear 11 meshes with the leveling roller rack 10 fixed on the side frame of the support frame 1, during the movement, the meshing transmission of the gear and the rack forces the leveling roller gear 11 to rotate, thereby driving the leveling roller 14 to rotate synchronously, realizing the rolling leveling operation of the product on the thick rubber plate 5.
[0026] Please see Figure 1 and Figure 3 Both sides of the upper flat leveling platform 8 are equipped with transverse telescopic cylinders. The movable end of the transverse telescopic cylinder is equipped with a clamping hand 9. When the thick rubber sheet 5 is transported to the lower part of the upper flat leveling platform 8 by the first displacement mechanism, the transverse telescopic cylinders on both sides of the upper flat leveling platform 8 are activated. The movable end of the cylinder extends and pushes the clamping hand 9 to move towards the thick rubber sheet 5, thereby clamping the thick rubber sheet 5 and making it firmly attached to the upper flat leveling platform 8, providing a stable foundation for the subsequent leveling operation of the product on the thick rubber sheet 5 by the leveling roller 14.
[0027] Please see Figure 1A leveling platform lifting position sensor 7 is installed on one side of the top plate of the support frame 1. The leveling platform lifting position sensor 7 monitors the lifting position of the upper flat leveling platform 8 in real time. When the platform lifting motor 6 drives the upper flat leveling platform 8 to move up and down, the sensor will feed back the platform's position information to the control system in real time. Once the platform reaches the preset position, the control system will issue an instruction in time to stop the platform lifting motor 6, ensuring that the upper flat leveling platform 8 stops accurately in the required position.
[0028] Working principle: First, the thick rubber sheet 5 is placed on the thick rubber sheet support tray 4. The support tray moving cylinder 2 retracts, and the support tray moving slider 3 drives the thick rubber sheet support tray 4 to move, sending the thick rubber sheet 5 under the upper flat plate leveling platform 8. At this time, the clamps 9 on both sides of the upper flat plate leveling platform 8 clamp the thick rubber sheet 5 under the action of the cylinder, so that the thick rubber sheet 5 fits against the upper flat plate leveling platform 8. Then, the roller platform moving cylinder 12 is opened, driving the leveling roller moving slider 13 equipped with the leveling roller 14 to move towards the thick rubber sheet 5. During the movement, the leveling roller gear 11 at one end of the leveling roller 14 meshes with the leveling roller rack fixed on the upright frame 1, so that the leveling roller gear 11 rotates while the leveling roller 14 rotates synchronously with it. When the rotating leveling roller 14 passes under the thick rubber sheet 5, it levels the product on the thick rubber sheet 5. After leveling is completed, the thick rubber sheet support tray 4 enters to remove the thick rubber sheet 5.
